Had the Fly Z+ with the Diamana Ka'li 60 and loved it until the head cracked where the sole and crown meet at the back of the club. Cobra replaced it no questions asked but sent me a new F6+. Sold it immediately as I did not like it at all. It felt dead compared to the Fly Z+. I was tempted to go with the LTD but went with the 2016 M2 and have not looked back.

... I think sound/feel has to be one of the most difficult aspects to "get right" for all OEMs especially when it comes to drivers. For me, the Fly Z+ was one of the worst sounding and feeling drivers I have ever hit. Tinny, loud, and the face just felt flimsy to me. Imo the best feeling/sounding modern head is the Epic with a very dense, thick face feel that I absolutely love, especially when the ball explodes off the face with a nice THUD not CRACK, and wish the F8 was similar. Of course others hated it and described it similar to your feelings about the F6+... dead. Obviously sound/feel is very personal and for every person that loves the sound/feel of any given driver, there is alway someone else that hates it.

... Long story short as I learned this lesson early in my reviewing career. I played a set of Hogan 99's for a few months and they were just too crisp feeling for me so I traded them in on some MP33's that gave me that soft, ball melt into the face feeling I love. My first day with the MP33's at the range, there was a kid about 25 yrs old hitting what looked like a new set of Hogan 99's right next to me. We both hit a 4 iron to a green and our balls hit each other which is pretty weird so I asked him about his irons. Turns out if was his first time hitting the Hogans and he traded in a set of MP33's because in his opinion they felt like "mush" and he loved the crisper feel and feedback of the 99's. It was a great learning experience for me about how different golfers have different opinions concerning sound/feel and I became more explanatory about sound/feel in my reviews.

I completely understand that everyone has a different interpretation of feel. The F6+ just felt hollow to me and the ball felt dead off the face compared to the Fly Z+. The ball seemed to jump off the face of the Fly Z+. I do not mind a solid feel to a driver as opposed to a hollow feel but I also want it really jumping off the face. I did not get that with the F6+. I'm current playing the 2016 M2 and it is a solid feeling driver with a muted sound, but the fall really jumps off the face.

... Yea, I think we all want the ball jumping off the face. It is amazing how a robot can get virtually identical ball speeds but we humans have a lot of variations from driver to driver. If it were as easy as one jumps off the face more than others, we would all be playing the same driver. I think this is what makes threads like this so interesting, reading about drivers you love and others hate or you hate but others love. One thing is for sure, there are just so many great drivers out there right now and it often comes down to a personal preference for most.

Can anyone say for exact what the difference is between the bio cell + and the fly z + besides the speed channel and movable weight? Has anyone opened them up and noticed an internal difference? Have both thinking about selling the bio cell + as it doesn’t have very many swings on it.

As I recall, there’s a slight difference in loft range. 8.0-11.0 on BioCell+, 8.5-11.5 on Fly-Z+. Both have a multi-material crown, the BioCell is venollum with the cell-like construction. Fly-Z+ crown is carbon fiber. Splitting hairs really. Speed channel doesn’t do anything. The real difference is the front-back weight adjustability, the resulting difference in sound & feel, and it’s effect on trajectory & dispersion.

I contacted Cobra about the 16 gram Fly Z weights. They still have some lying around even though they aren’t listed on the website. They ended up helping me out over the phone to get one ordered. They do end up being expensive though - $35 after shipping and tax, but probably worth it to get a legit one over the $19 China ones on eBay.

I did the same last week via email and the Cobra rep asked me for my mailing address. They put one in the mail for me and did not mention anything about $$. I expect to receive the weight any day now.

I too received a free weight using the above email. Mine was for a just purchased F8 Tour Length driver. It came with a 16g and 2gr weight. I wrote in to ask why I received a 2gr weight when the website says the tour length ships with a 16gr and 6gr. I said the driver felt lighter to me than what I was using at the demo day. The rep immediately offered to mail me the 6gr weight. It showed up a week later. Excellent service.

Sounds like you reached a better rep than me. What e-mail address did you use? I just contacted the main one on the website and ended up connecting with a guy named Sean.

The weight came in the mail today free of charge. The only question I have is there is no marking on the weight itself indicationg it is 16 grams. Looks identical to the original weight I had in the driver. How does one tell?

... I have three 16gm weights and the copper one says 16 on it, but the 2 gold ones do not have any number. They look like this with the 8gm weight on the left and the one on the right is the 16gm weight:

Took my Fly Z driver out to the range today. Replaced the stock 8 gram weight with the 16 gram weight. I have this club mated with adila dvs (r flex) at 45 inches. Hit some good and some so so drives. Club felt pretty heavy. Will take it out a few more times to test out but my preliminary thoughts are to cut it down to 44.5,

I am assuming if I do this the shaft will play a tad stiffer but it will be lighter. May be it will be close to the overall weight when playing at the original 45 inches and the 8 gram stock weight. Am I somewhat correct here or totally off base?

... I have always felt that when adding weight to the head it makes the shaft play a little softer, which offsets the increased stiffness from cutting it shorter. I am very much a feel player and a shaft that is too stiff makes me loose my tempo because i feel like I need to swing harder to get the shaft to unload. So the heaver head combined with a shorter shaft has been a good combo for me, especially in the Fly Z.

as mentioned previously yes your thought process is correct but only if you didn't add head weight, the 8g you added to the head will more than offset the stiffness increased by shortening the shaft. when shortening the shaft from the butt section you are removing a stiffer part of the shaft, this coupled with the increase in head weight you are essentially soft stepping the shaft which would be putting a 5 iron shaft in a 6 iron because the 5 iron head is lighter than the 6 iron head the added weight of the 6 iron head makes the shaft play softer even though it is cut to 6 iron length. you may already know this but I thought I would add my two cents. great to hear people are still using this great club, keep it on the fairway
